DIN EN 14572 Pedestrian Headform Impact Crash Test
The DIN EN 14572 pedestrian headform impact crash test is a critical component in automotive safety testing, designed to evaluate the potential risk of injury to pedestrians during a vehicle collision. This test simulates real-world scenarios where a pedestrian may come into contact with a moving or stationary vehicle. The primary objective is to assess the effectiveness of various countermeasures that automakers implement to mitigate these risks.
This standard is widely recognized and adhered to in Europe for its robust methodology, which ensures consistent and reliable results across different testing facilities. The test involves the use of anthropomorphic test devices (ATDs) known as pedestrian headforms designed according to ISO 7804-1:2015. These headforms are subjected to controlled impacts at specific velocities using a moving wall or sled system.
The test is particularly important in the automotive industry, especially for those involved in vehicle design and manufacturing. Compliance with this standard not only ensures safety but also aids in meeting regulatory requirements set by various national authorities and international organizations. For instance, the European New Car Assessment Programme (EURO NCAP) often incorporates results from these tests to rate vehicles.
The test setup typically includes a test rig that can accommodate different vehicle configurations and pedestrian headform positions. The moving wall or sled system is designed to replicate the impact of a vehicle against an immovable object, such as a curb or parked car. The impact velocity is carefully controlled to simulate common crash conditions, with typical speeds ranging from 5 km/h up to 20 km/h.
The test procedure involves several key steps:
- Positioning the pedestrian headform in a predefined location relative to the vehicle.
- Initiating the moving wall or sled system at the specified velocity.
- Monitoring the impact and subsequent motion of the headform.
- Evaluating the deformations and accelerations experienced by the headform during the collision.
The results are analyzed to determine compliance with predefined criteria, which include maximum allowable acceleration levels and deformation limits. These parameters are crucial for assessing the vehicle's ability to protect pedestrians in the event of a crash.
| Parameter | Description |
|---|---|
| Impact Velocity | Range: 5 km/h to 20 km/h, depending on test configuration. |
| Headform Positioning | Defined according to ISO 7804-1:2015, ensuring accurate replication of real-world scenarios. |
| Measurement Criteria | Maximum allowable acceleration levels and deformation limits specified in the standard. |
The importance of this test cannot be overstated. It directly impacts public safety by providing manufacturers with critical data to improve vehicle designs. Compliance ensures that vehicles meet stringent regulatory requirements, enhancing trust among consumers and regulatory bodies alike. Understanding these tests is essential for quality managers, compliance officers, R&D engineers, and procurement teams involved in the automotive sector.
